This is also easy: 
  (my $verbose='');

This is an empty list (or better, a list containing that particular piece of emptiness referenced by $verbose.

You might call it easy, but it's wrong. Twice. First of all, parenthesis do NOT make lists. Context makes lists. Parenthesis are used for precedence.
Furthermore, if the context would demand a list (which in this case it does), it's not an empty list. How could it be? There's a scalar inside it. It's a one element list.
